Intel Iris Graphics Performance With Mesa 10.6

With GpuTest synthetic OpenGL workloads the results were unchanged except for the pixmark benchmarks -- both Pixmark Piano and Pixmark Volplosion. For these GpuTest Pixmark benchmarks, the Mesa 10.6 performance is much higher than 10.5.2 stable atop Ubuntu 15.04 x86_64 with the Linux 4.1 kernel.

At the end of the day there doesn't appear to be any broad performance improvements for Mesa 10.6 as it pertains to Intel Haswell/Iris Graphics, but in certain workloads like GpuTest Pixmark, Unigine Tropics, and Xonotic (Low), the performance did rise. While there's no jaw-dropping performance gains, at least the Intel Mesa driver is still moving forward with OpenGL ES 3.1 / OpenGL 4.x support, Skylake / Cherry Trail enablement, the conversion to NIR, and other non-performance-related improvements.
